PROCESS OF DYEING SAND.

K Drawing. Application filed January 18, 1924, Serial 8'0. 687,139, and in Canada March 21, 1828.

It has been found that very fine sand can be advantageously used in making decorative designs, such as frames, seats, walls, columns and so forth, but since this sand I is of a uniform color, it is rarely used for this purpose, It is therefore necessary to impart various colors to the sand, such as by dyeing, but the difficult is that the sand is not susceptible to yeing by the 10 ordinary. process because of its vitreous structure. I have found as a result of numerous expernnents that sand can be successfully dyed any desired color vby the process herein disclosed.

For exterior work I- employ a dyeing composition consisting of paint, oil and turpentine, the proportions varying according to the color or shade to be obtained. I mix these ingredients and immerse the sand 2 in the mixture, allowing it to soak for a suitable period of time. The sand is then removed and allowed to dr for about 24 hours. Finally it is rolle with a hard wooden roller.

In using the sand thus colored for decorative purposes, the surface to be decorated is given a coat of glue, shellac or similar substance. The colored sand is then applied and adheres firmly to the surface. I can apply the colored sand as-well to ordi- 3e nary -fabric, satin, wood, clay, brass, cardboard, or any other surface.

' For interior work the sand is dyed in the same manner, but with ink. Although a specific embodiment of the invention has been described, it will be understood that the proportions may be varied within wide limits without detracting from i the utility of the invention or departing from the scope thereof as indicated by the 4 applended claim.

. aving thus. fully described the inven tion, what I claim as, new and desire to protect by Letters Patent is The herein described process of dyeing sand consisting in soaking sand in a mixture of paint, oil and turpentine, removing the sand, drying it, and rolling it.

In witness whereof I have hereunto set my hand.
